About our fire rated sealant in Watton at Stone
We do not assess buildings or decide what fire stopping is needed; your assessor, designer or building control sets that out. What we do is apply the right product to that specification, properly and neatly. Common call-outs are for holes left by a change of layout and linear gaps at the head of walls, on pipe & cable gaps, plasterboard & masonry and flats & HMOs.
Somewhere as small as Watton at Stone, commercial jobs tend to be pubs, holiday lets, farm buildings or halls rather than offices. Each still needs sound sealant in its washrooms and kitchens, and fire-rated joints where services pass through walls.
There’s a 12-month guarantee on every job, large or small.

What happens if it’s left?
An open gap in a fire-resisting wall is a route for smoke and fire. Sealing it properly restores what the wall was there to do, and the sealing itself is often a contained piece of work. In a small place like Watton at Stone, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part, and we will explain the quote if you ask.

Do you need fire rated sealant in Watton at Stone?
Sometimes the wrong product was used from the start: ordinary expanding foam, standard silicone or decorators’ caulk in a place that needed a tested fire seal. It looks sealed, but it isn’t fire-rated.
Signs it’s time to call us include:
- Gaps around pipes and cables through fire-resisting walls
- Seals cut through by electricians, plumbers or data installers
- Cracked or shrunken fire-rated sealant
- Standard silicone or caulk in a fire-stopping gap
For buildings such as Church of St Andrew and St Mary, older buildings that have had new heating or wiring often have service gaps worth checking.
Before booking anyone
- How the surfaces are prepared before sealing
- How long the guarantee is
- How hidden problems are handled
- Whether they seal over old material or remove it
Looking after it afterwards
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Check whether a sealant can be painted before decorating over it
- Keep the record of products and locations with your fire safety documents
- Look in service cupboards and ceiling voids from time to time
- Keep general-purpose foam and caulk away from fire-stopping gaps
File the record of locations and products with your fire safety paperwork. It saves time at the next inspection or assessment.
When you plan work that goes through walls or ceilings, plan the fire stopping too. Doing it at the time avoids leaving gaps behind.
When it is not the sealant
Some problems need a builder, plumber or other trade rather than us:
- Openings too large for sealant, which need batts, boards or another system
- Issuing a fire rating or certificate for a building
- Deciding what fire stopping a building needs
If you’re not sure, just call 0345 464 0079 or drop us an email and we will give you a straight answer before you book.

Plasterboard walls
Holes in plasterboard are often cut roughly for services. Where a hole is bigger than the sealant’s tested range, it needs another approach, and we will tell you.

A linear joint may need to allow for movement as well as fire. We choose a product and depth that suit the gap and the movement from the manufacturer’s details.
